Izitho zokuzala ziloo malungu enoxanduva lokuzalwa komntu. Ngale mizimba, inkqubo yokuchumisa kunye nokunyanyiswa komntwana, kunye nokuzalwa kwakhe, kwenziwa. Izitho zokuzala abantu zihluke ngohlobo lwesini. Oku kubizwa ngokuba yi-sex dimorphism. Inkqubo yamalungu omzimba wesetyhini iyanzima kakhulu kunokuba yindoda, kuba umsebenzi obaluleke kakhulu wokuthwala nokuzala umntwana uwela kumfazi.
Ulwakhiwo lwezitho zentombi zobuncwane
Izitho zenkqubo yokuzala yabasetyhini zinalolu hlobo lulandelayo:
- i-genitalia yangaphandle (i-pubis, i-labia enkulu kunye encinci, i-clitoris, i-vestibule, iintlanzi ze-Bartholin);
- Izitho zangasese zangaphakathi (ubunqunu, amaqanda, iimbumba, izibilini ze-fallopian, isibeletho).
I-anatomy yamalungu esetyhini okuzala inzima kakhulu kwaye ihloselwe ngokupheleleyo umsebenzi wokuzala.
Imizimba yokuzala yabasetyhini
Amalungu omgangatho wokuzala owenziwa ngabafazi:
- I-Lobok - inxalenye engezantsi yodonga lwangaphakathi lomzimba, olukhupha ngenxa yokuphuhliswa kwecatter fat-layer, eneenwele ezigubungeleyo.
- Izindebe zomzimba zesondo, ezikhupha izikhalazo zomzimba kumacala omabini, zahlula kwizinto ezibizwa ngokuba yi-labia encinci nangaphezulu. Injongo yalezi ziko kukudala ukukhuselwa komatshini wokungena kwesini, kunye nephepha lomchamo. I-labia enkulu, efana ne-pubis, ine-scalp, ngelixa i-labia encinci ayinayo. Banobuhle bebhinki, banomlinganiselo okhulayo weengqungquthela ezizimeleyo, izibilini kunye nokuphela kwezicathulo.
- I-clitoris yilungu elijongene nokuvakalelwa ngokwesini kwowesifazane, esekwe kwimigangatho ephezulu ye-labia minora.
- Umyinge wesini ngumhlaba obonakala ngathi unqabileyo, olinganiselwe kumacala omabini ngama-labia, kunye ne-clitoris kunye ne-posterior verticulation of labia. Ukuvula kwangaphandle kwe-urethra kuvulwa kulo mbutho. Isango lomfazi lenza umsebenzi wezesondo, ngoko ke luyakhathalela kunoma yimuphi umnxeba.
- Iintlanzi zeBathoholin zizitho zentombi zobuncwane ezisebunqeni besiseko sezintlu zesini somzimba, esenza i-vaginal fluid ngexesha lokuvusa isondo.
- Ibhinqa lilungu langaphakathi elithatha inxaxheba kwisondo kunye nokubeletha. Ubude balo buphakathi kweesentimitha eziyi-8. Ngaphakathi kwalo mzimba uhlanganiswe ne-membrane ye-mucous kunye neentlobo ezininzi, ezinika ubulili amandla okwelula ngexesha lokubeletha.
- Ama-ovane yilezi zihlunu zokuzala zowesifazane owenza umsebenzi wokugcina amaqanda elinde ixesha lawo. Njalo inyanga, iqanda elivuthiweyo liphuma kumaqanda, lilungele ukuchumisa.
- Izibilini ze-Uterine - iibhubhu ezingenangqungquthela, ezisecaleni elincinci nangesinceleni kwaye zivela kuma-ovari kunye nesisu. Kuzo uququzelelo okanye ukulungelelanisa i-ovum yenza indlela yayo.
- I-uterus yilungu lomzimba eliphambili elinomfanekiso wepeyari. Iqukethe ngokupheleleyo imisipha kwaye ijoliswe ekuthwaleni umntwana.
- Umlomo wesibeleko uyinxalenye engaphantsi kwesibeletho evulekayo kwisini. Kubalulekile ukukhulelwa kunye nokubeleka.
Izithako zezitho zokuzala
I-Ultrasound yezitho zokuzala iyona ndlela ebaluleke kakhulu yokufumanisa izifo ezahlukahlukeneyo ezichaphazelekayo. Ikhuselekile, ayibuhlungu, ilula kwaye idinga ukulungiswa okuncinci. I-Ultrasound yeenxalenye ze-pelvic ibonelelwe ngenjongo yokuxilonga (kubandakanya emva kokukhipha isisu nangesikhathi sokukhulelwa), kunye nokwenza amanyathelo angenelelo afuna ukulawula okubonakalayo. Abasetyhini banokufumana i-ultrasound of organism reproductions or transabdominally. Indlela yokuqala ibhetele ngakumbi, kuba ayifuni ukuzaliswa kwesilwanyana.
